Net Core中使用Newtonsoft.Json進行序列化保持原有大小寫

  JsonSerializerSettings settings = new JsonSerializerSettings();

    //EF Core中默認為駝峰樣式序列化處理key
    //settings.ContractResolver = new CamelCasePropertyNamesContractResolver();

    //使用默認方式，不更改元數據的key的大小寫

    settings.ContractResolver = new DefaultContractResolver();

    return Json(data, settings);

全局設置，Json序列化配置

public void ConfigureServices(IServiceCollection services)

{

    // Add framework services.

    services.AddMvc()

        //全局配置Json序列化處理

        .AddJsonOptions(options =>
        {

            //忽略循環引用

            options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;

            //不更改元數據的key的大小寫

            options.SerializerSettings.ContractResolver = new DefaultContractResolver();


        }

        );

}
